Kernel Compilation Errors: 'undefined reference'

Kernel Compilation Errors: 'undefined reference'

Post by paul coluc » Sun, 04 Feb 1996 04:00:00

   I just installed Slackware 3.0 and everything went OK.  I have
a Mitsumi FX400 ATAPI IDE.  I used the idecd bootdisk to install
the files off the CDROM onto my hard drive.  When the installation
was completed, I did not have CDROM support anymore; I assume (?)
that the kernel loaded on the installed system did not have ATAPI
IDE CDROM support (I checked /proc/devices and the cdrom did not
show up, although the iso9660 format showed up under /proc/filesystems).
I rebooted with the idecd bootdisk and text rootdisk and then I
regained the CDROM back, so I think that CDROM support was not on
the final installed kernel.

  At this point I decided it was a good time to recompile the kernel
with support for my Mitsumi ATAPI IDE support as well as support for
my Pro Audio Spectrum 16 Basic sound card.  I have read the relevant
HOWTO's faithfully.  I did 'make config', 'make def' and 'make clean'.  
I also ensured I had the proper symbolic links to linux and asm.  When
I finally got to 'make zImage', the machine (dx4-120 PCI, 8MB RAM) crunched
around for about 20 minutes, and then choked with many, many, (many!)

                           undefined reference to

statements, and finally

                       make: *** [vmlinuz] Error 1.

I went through the procedure 2 more times with identical results.

The final time, I piped the output of the compilation procedure
to a file.  Below are relevent excerpts from that file:

   If anyone has any suggestions I greatly appreciate it.
